Hi I am having trouble with getting my CMX512-3200C2PT module to work properly on my K8V Deluxe Mobo. I constantly get windows errors while running it in my system. I'v read the forums and did everything needed such as increasing the Voltage to 2.7. And trying it in different slots. I put in a different stick of ram temporarily and everything works great. If it makes a difference, it used to be a twinX kit which I used to be able to run but only at 333mhz, I figured it was because it is a single-channel mobo. I pulled one out to put into a newly built system that i keep at a different location and that one works fine a it's full 400mhz and tight timings. So I think that it's just a bad module.

My Bios settings are as follows:

memort clk: 200mhz

tcl: 3

trcd: 4

tras: 8

trp: 4

trrd: 2

trc: 12

trfc: 14

trwt: 4

read preamble: 5.5ms

asunchronous latency: 7ms

memlock mode: limit 2:1 (ddr400)

bank interleaving: auto

TWR: auto

ddr clock delay: auto

2t command: disabled


Also, it has all the timings greyed out and i'd like to know if i there's a way to change them without an older bios which will not support the processor. Currenly it's:1010.

Please install the modules in slots 1-3 or 2-3 and then load setup defaults and set the following settings and test the modules with http://www.memtest.org.

memort clk: 200mhz

Dim Voltage to +.2 Volts:

CAS Latency CL=2.0

Row Cycle Time tRC Bios Default

Row Refresh Cyc Time tRFC Bios Default

Ras# to CAS# delay tRCD 3

Row to Row delay Bios Default

Min Ras# Active Time tRAS 6

Row Precharge Time tRP 3

Write Recovery Time Bios Default

Write to Read delay Bios Default

Read to Write Delay Bios Default

Refresh Period tREF Bios Default

Enable 2T Timing Enabled

Then test the system with http://www.memtest.org and make sure it's stable!

Any setting not listed should be set to bios default.
